Method to calculate overlap scoring
\[\begin{split}Score = -(\lvert begin_{1} - begin_{2} \rvert + \lvert end_{1} - end_{2} \rvert + \begin{cases} 0, & if label_{1} = label_{2} \\ 2, & otherwise \end{cases})\end{split}\]See also

For a detailed example that using this metric
- Parameters:
first_element (
CtmInterval
) – First CTM interval to comparesecond_element (
CtmInterval
) – Second CTM intervalmapping (Optional[dict[str, str]]) – Optional mapping of phones to treat as matches even if they have different symbols
- Returns:
Score calculated as the negative sum of the absolute different in begin timestamps, absolute difference in end timestamps and the label score
- Return type:
